7 'o aid '71) item may ooiwem Be it known that l, Josnrnt Cosrnn'ro, u citizen of the United States, and a resident of the city of Alhany in the county of Albany and State of New York, have made certain new and useful improvements in Non-ellipping holes, of which the following is a'. specification.

As well known, the sole of an ordinary shoe or boot is made of leather and has a flatsurface. lfiolcs of thischarecter give the wearer slight assistance in steadylng lnnl sell on a slippery, sidewalk or road unless he same be provided with some means to. prevent slipping. Moreover the sole of a shoe of the usual type possesses no resilient or cushioning properties of any degree. To prod'oce an attachment for soles that will have resilient qualities and also prevent the wearer from slipping is the object of my in. vent-ion.

lln my invention, I have in ii sense utilized the theory of the hoof of a horse in )1'0- ducing a 'deviceto prevent sliding or slipping when the same is attached to the sole or a shoe or boot Worn by the wearer.

my one who will examine a liorsesihoof will see that the bottom at the sanie is not a plain surface or a flat surface as is the case with the other 'words, there is e depression in the hoot oi. a horse that enables him to obtain a lirin grip on a dirt highway.

I have utilized this principle in the pruduction of my sole attachment and in constructing the same form it preferably in a U shape substantially, or, in other words, on the general lines of a horse shoe. By a U or horseshoe shape, linean any construction that wheirapplicd to the sole of a boot or shoe permits of an open space being, formed between different sides of the attachment, this space being open at one end or entirelyyclosed by ti my attachment according to the manner in which the arms of the attachment are bent or inai'iipula-ted when the said attachment is fastened to a sole as will be subsequently pointed out.

most important feature of my inven tion lies in the provision of means by which the attachment may he quickly and easily attached to a. solo by numher of fastening devices and moreover by which a tight joint between the sole and earns PAT Spccificetlon 01 Letters Patent.

Lon-slipping andv Wearing devices may,

a cross-section Fig. is a top l a sec-non on line e e of Fig. l and Fig. 5 another View of iny device.

In said drawings: the numeral 1 denotes a non-slippiug attachment of a configuration comprised ijithin my invention.

The attaclinientl is hil'ur rated, that is to sey,-it has two longitudinal sides 5? and 3, which are connected together by what I may call," for pui poses of description, n transverse portion l.

My improved non'slipping attachment may be quickly attached to the bottom of a shoe or boot by nailing the same in place. As willv readily be understood and as previously referred to, by having the under side of the device as at 8 concave in cross-section it will be clear that a minimum numand as when the device is nailed the same is flattened this concave portion 8 will cause the attachment to make a very tight joint with the sole of a boot or' shoe. This feature I regard as very important as it will be readily seen that my attachment can be quickly nailed in place and that there will be no occasion for sewing or cementing as is usually the fact when attachments of this type are placed in position on the soles of boots or shoes. It will -furthermore be clear from an inspection of Fig. 1 that inasmuch as the device is made of resilient material the portions 2 and 3 of the device will or .may be moved toward or from one another to fit various sizes of shoes. It will also be clear that there will always be an air pocket or an air space 10 left between the device and that this space will be closed at one end and open more or less at the other end, that is to'say, the size of the opening into the air space formed by the walls of the device when the same is attached to a shoe will depend upon the distance between the parts 2 and 3 when the same are adjusted to the size of the shoe. It will be clear, however, that when my device is in place the 2 and 3 may be septhe sides ofarated or under certain conditions they may meet. In the latter contingency the air space 10 would be closed. It will be clear, however, that the type of attachment illustrated and described in this application is of a resilient bifurcated type that is capable of adjustment to various sizes of shoes or boots and that by reason of its concave under surface is capable of being tightly applied to the bottom of a boot or shoe.

When in place and in use the resilient qualities of the device afford the user ease in walking and the configuration of the attachment providing, moreover, the space 10 affords means for the prevention of slipping.

The sides of the device may be carried to rather a sharp edge as shown at the portions 11 forinstance in Figs. 4 and 5. When thus fashioned the attachment is difiicult to see when attached to the sole of a boot or shoe, that is to say, when viewed from the side.

From an inspection of Fig. 5 it will also be seen that the said attachment is shown convexed longitudinally. It will also be seen thatT have shown the attachment as convexed on its top surface. By convening the attachment longitudinally as a whole facility is afforded for attaching it to the sole of an ordinary boot or shoe which is always more or less bent.

Having illustrated and described my invention, what I claim as new and desire to secure by Letters Patent of the United States is as follows:

1. A non-slipping attachment for shoe soles which is made of resilient material of a U or horse shoe shape substantially, said attachment having its attaching surface concaved or hollowed out, intermediate its entire periphery, and its tread .surface convex in cross-section, the entire sole being convex longitudinally on its tread face and concaved longitudinally on its attaching face.

2. A non-slipping attachment for shoe soles which is made of resilient flexible material and of U or horse shoe shape, the said attachment having its attaching surface c'on caved or hollowed out, intermediate its periphery, and its tread surface convex in lateral cross-section. substantially as described.
